class_docstr: Basic building block class for both :class:`BaseDataChunk` and :class:`BaseDataset`
  
  Notes
  -----
  Defines core callback method scaffolding, characterized by the following default behaviors:
      * Eight core callback methods call :meth:`BaseDataCore._on_call_default`
      * :meth:`BaseDataCore._on_call_default` does nothing
      * :meth:`BaseDataCore._do_something` calls the appropriate core callback method
docstr: Basic/fallback logic for invocation of primary callback methods
  
  Parameters
  ----------
  division: {"exp", "rep", "fold", "run"}
      Time span division identifier of the primary callback method to be invoked
  point: {"start", "end"}
      Time span point identifier in `division` of the primary callback method to be invoked
  *args: List
      Positional arguments to provide on invocation of the specified primary callback method
  **kwargs: Dict
      Keyword arguments to provide on invocation of the specified primary callback method
  
  Notes
  -----
  This method's primary utility is providing a unified handler for any unmodified invocation
  of a primary callback method. This is possible because the default behavior of the primary
  callback methods defined herein is to simply call :meth:`BaseDataCore._on_call_default`
  
  This method should not be invoked anywhere other than in the primary callback methods
  defined in this :class:`BaseDataCore`. In general, it should only appear elsewhere if it
  is being overridden by a subclass of :class:`BaseDataCore`
